Alcohol in the Body

• Once alcohol is swallowed, it goes to the stomach
  and then the small intestine
• From stomach and SI, it is absorbed into
  bloodstream
• Travels to all cells and tissues, including the
  brain (effects are felt within minutes)
• Eventually reaches liver, where broken down to
  carbon monoxide and water
• The more you drink, the harder your liver has to
  work (one hour to break down alcohol in one
  bottle of beer)

  no longer is able to metabolize food properly
• People with cirrhosis who continue to drink have
  only 50 chance of living more than five years
